Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If an insertable electronic device is abnormally fastened by a fastening member, then the device may be physically secured, but electric stability is compromised due to failure of ground pad contact, leading to signal quality degradation

Engineering Contradiction:
Improvefastening strengthVSAvoidelectric stability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent implements a detection circuit that monitors whether the ground pad contact is properly established. When abnormal fastening prevents ground contact, the detection circuit generates a detection signal that triggers an error message or operation restriction, providing feedback to the user or system about the improper installation state.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs ground pad contact detection before allowing normal operations to proceed. The detection circuit checks the electrical connection status in advance, and only permits operations when proper ground contact is confirmed, preventing potential signal quality issues before they occur.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If ground pad contact is not established between insertable device and host device, then device insertion is simplified, but electric stability cannot be secured, causing operation degradation

Engineering Contradiction:
Improveinsertion easeVSAvoidelectric stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The detection circuit provides immediate feedback when ground pad contact is absent or improper. The system monitors the electrical connection status and generates appropriate responses such as error messages or operation restrictions, ensuring users are notified of improper installation without complicating the insertion process itself.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically detects and responds to ground pad contact status without requiring manual verification. The detection circuit self-monitors the electrical connection and autonomously triggers appropriate responses, eliminating the need for users to manually check connection status.

Inventive Principle:
Principle #25Self-service

3Reliability

If fastening structure is added to ensure ground pad contact, then electric stability is improved, but device complexity increases

Engineering Contradiction:
Improveelectric stabilityVSAvoidfastening structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical fastening verification mechanisms with an electrical detection circuit. Instead of using mechanical sensors or switches to verify proper fastening, the system uses the electrical properties of the ground pad connection itself to detect installation status, simplifying the overall structure while maintaining reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ground pad serves dual functions: it provides the necessary electrical ground connection for signal stability and simultaneously acts as a sensor for detecting proper installation. This multi-functionality eliminates the need for separate detection mechanisms, reducing device complexity while ensuring electric stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
